Detailed Description

In order to facilitate better understanding of the present invention for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, which are given by way of illustration only and thus do not limit the scope of the present invention.

As shown in fig. 1-3, the double-shaft differential mixer according to the embodiment includes a base 1, wherein a mixing tank 2 is disposed on the base 1, a feeding port 3 is disposed at an upper portion of one end of the mixing tank 2, and a discharging port 4 is disposed at a bottom portion of the other end. Still be equipped with speed reducer 5 on the frame 1 and this speed reducer is equipped with the output shaft of two different rotational speeds, be equipped with the (mixing) shaft 6 of two parallels in the stirred tank 2, the one end of two (mixing) shafts 6 all rotates through bearing frame 10 and sets up on frame 1, the other end is connected on two output shafts of speed reducer 5 through shaft coupling 11 respectively, speed reducer 5 is rotated in order to drive two (mixing) shafts 6 by motor drive, specifically, the motor rotates and drives two motor wheels 13 and rotate to drive speed reducer 5 and rotate, and then drive the (mixing) shaft 6 rotation with two output shaft connections of speed reducer 5. In order to increase the strength of the stirring shaft 6, holes are not formed in the stirring shaft 6, so in the embodiment, a plurality of shaft sleeve assemblies are uniformly distributed on each stirring shaft 6 along the axial direction, each shaft sleeve assembly comprises a first shaft sleeve 7 and a second shaft sleeve 8 which are detachably and fixedly connected together, specifically, the first shaft sleeve 7 and the second shaft sleeve 8 are connected through a fastening piece, the shaft sleeves 7 and the second shaft sleeves 8 on every two adjacent shaft sleeve assemblies are connected through bolts, the mounting positions of the first shaft sleeve 7 and the second shaft sleeve 8 are opposite, namely, the first shaft sleeve 7 and the second shaft sleeve are just opposite to each other to form an included angle of 180 degrees, the stirring knife 9 is detachably fixed on the first shaft sleeve 7, specifically, the stirring knife 9 is detachably fixed on the first shaft sleeve 7 through the fastening piece, through the structure of the shaft sleeve assemblies, firstly, the stress concentration of the stirring shaft 6 can be reduced, the stability of the product structure is improved, if the stirring knife 9 and the stirring shaft 6 are integrally fixed, the stirring knife 9 is difficult to replace, the whole stirring shaft 6 generally needs to be replaced, but the shaft sleeve assembly structure is adopted, so that the shaft sleeve connected with the stirring knife 9 can be directly replaced, and the convenience is realized, and the cost is greatly saved; in addition, because the installation positions of the first shaft sleeve 7 and the second shaft sleeve 8 are opposite, the directions of the stirring knives 9 on every two adjacent shaft sleeve assemblies are also opposite, and the raw materials can be fully mixed.

In this embodiment, in order to avoid interference between the stirring blades on the two stirring shafts, a third shaft sleeve 12 is provided at one end of one of the stirring shafts 6 close to the speed reducer 5, and the stirring blades 9 on the two stirring shafts 6 can be staggered by installing the third shaft sleeve 12.

Preferably, the speed reducer 5 is arranged at one end close to the feeding hole 3, and correspondingly, the output shaft of the speed reducer is also arranged at one end close to the feeding hole, so that the mixer is simpler in structure, less in corresponding parts and more convenient to mount.

Further, the included angle between the stirring blade 9 and the stirring shaft 6 is 15 degrees.

Furthermore, the two stirring shafts 6 are round shafts, so that the axial limiting is facilitated by the round shafts, and the rotating resistance of the stirring shafts is small.

The working process of the double-shaft differential mixer in the embodiment is as follows: the starter motor, the motor rotates and drives two motor wheels 13 and rotate, thereby drive speed reducer 5 and rotate, and then two (mixing) shafts 6 that drive and two output shaft of speed reducer 5 rotate, the direction of rotation of two (mixing) shafts 6 is in opposite directions, the raw materials that fall feed inlet 3 constantly carry out the homogeneous mixing stirring, there is certain angle of inclination between (mixing) shaft 6 last stirring sword 9 and the (mixing) shaft 6, can push the raw materials of stirring through the abundant stirring in stirred tank 2 to discharge gate 4 like this in the stirring, because the rotational speed of two (mixing) shafts 6 is different, so the raw materials in stirred tank 2 is through stirring sword 9 times and intensive stirring back, not only the mixing stirring effect is better, and speed is faster, make output higher.

The foregoing has described only the basic principles and preferred embodiments of the present invention and numerous changes and modifications may be made by those skilled in the art in light of the above teachings and shall fall within the scope of the present invention.
